The homepage of my PhD supervisor, Andrei. A. Agrachev

Many interesting papers on Subriemannian Geometry, Topology of quadratic mappings, Symplectic Geometry.

The homepage of my mentor at Purdue, Saugata Basu

Plenty of papers on (homological) complexity of semialgebraic sets.

The homepage of my friend Davide Barilari

There are many interesting papers on the geometry of heat kernels and volumes of Subriemannian Manifolds. You can also find the hamiltonian viewpoint lecture notes on Subriemannian Geometry.

The homepage of my collaborator and friend Erik Lundberg

A very rich page, containing the lucid exposition on our current research program on Random Algebraic Geometry (direct link here).

Here are some nice videos of talks given at AskoldFest in Moscow 2012 for the conference Algebra and Geometry (mine is here).
